Kryptering

Encryption

Kryptering gör att man kan

  • skicka krypterad e-post, oläsbar för andra än avsändaren och mottagarna
  • kryptera dokument
  • kryptera hårddiskar och USB-minnen
  • signera dokument
  • säkerställa avsändarens identitet
  • säkerställa att information inte är ändrad
  • göra information oläsbar för ej behörig

Digital signering

  • Kontrollerar att avsändarens identitet är äkta
  • Kontrollerar att innehållet inte är förändrat efter signeringen

Encrypted or digitally signed e-mail

An encrypted message ensures that only the intended recipient can read it. For more information, see how to encrypt e-mail.

Digitally signed e-mail makes it possible for the recipient to check that it definitely is you that sent the e-mail. It also facilitates for the recipient to send you encrypted e-mails.. For more information, see how to digitally sign e-mail.

Encrypting hard drives and USB sticks

  • USB sticks and external hard drives usually come with encryption capabilities available
  • Windows PCs have BitLocker installed, but it usually needs activation
  • Macintosh/MacOS computers have filevault installed, but it usually needs activation
  • Most Linux systems have encryption capabilities;
    • Full-disk encryption (FDE), encrypting the block device before it is mounted on the system. FDE is usually included in the Linux distribution
    • File-based encryption, where only a folder or file is encrypted using native filesystem features.
  • Other operating systems may have encryption capabilities as well.
